Narrowband FM Coilless
Detector IF Subsystem
The MC13150 is a narrowband FM IF subsystem targeted at cellular and
other analog applications. Excellent high frequency performance is
achieved, with low cost, through use of Motorola’s MOSAIC 1.5™ RF bipolar
process. The MC13150 has an onboard Colpitts VCO for Crystal controlled
second LO in dual conversion receivers. The mixer is a double balanced
configuration with excellent third order intercept. It is useful to beyond
200 MHz. The IF amplifier is split to accommodate two low cost cascaded
filters. RSSI output is derived by summing the output of both IF sections. The
quadrature detector is a unique design eliminating the conventional tunable
quadrature coil.
Applications for the MC13150 include cellular, CT–1 900 MHz cordless
telephone, data links and other radio systems utilizing narrowband FM
modulation.
• Linear Coilless Detector
• Adjustable Demodulator Bandwidth
• 2.5 to 6.0 Vdc Operation
• Low Drain Current: < 2.0 mA
• Typical Sensitivity of 2.0 µV for 12 dB SINAD
• IIP3, Input Third Order Intercept Point of 0 dBm
• RSSI Range of Greater Than 100 dB
• Internal 1.4 kΩ Terminations for 455 kHz Filters
• Split IF for Improved Filtering and Extended RSSI Range

Receiver Design Considerations
The curves of signal levels at various portions of the
application receiver with respect to RF input level are shown
in Figure 17. This information helps determine the network
topology and gain blocks required ahead of the MC13150 to
achieve the desired sensitivity and dynamic range of the
receiver system. The PCB is laid out to accommodate a low
noise preamp followed by the 83.16 MHz SAW filter. In the
application circuit (Figure 15), the input 1.0 dB compression
point is –10 dBm and the input third order intercept (IP3)
performance of the system is approximately 0 dBm (see
Figure 18).
Typical Performance Over Temperature
Figures 19–26 show the device performance over
temperature.
